Abstract

A marking system for decorating one or more workpieces includes a plurality of marking stations that can mark product images on blank workpieces to produce product workpieces, at least some of which have different sizes, shapes, materials, or a combination thereof, a control system that can select one of the plurality of marking stations and send product image data to the selected one of the plurality of marking stations, and a robotic manipulator that can transport a blank workpiece to the selected marking station under the control of the robotic manipulator. The selected marking station can mark the product image the blank workpiece based on the product image data which produces a product workpiece. The robotic manipulator can remove the product workpiece from the selected one of the plurality of marking stations.

First claim

What is claimed is:

1. A marking system for decorating one or more workpieces, comprising:
a plurality of marking stations configured to mark product images on blank workpieces to produce product workpieces, at least some of which have different sizes, shapes, materials, or a combination thereof;
a control system configured to select one of the plurality of marking stations and send product image data to the selected one of the plurality of marking stations, wherein the control system includes data storage configured to store product images and blank workpiece identification codes; and
a robotic manipulator configured to transport a blank workpiece to the selected one of the plurality of marking stations under the control of the robotic manipulator,
wherein the selected one of the plurality of marking stations is configured to mark the product image on the blank workpiece based on the product image data which produces a product workpiece,
wherein the robotic manipulator is configured to remove the product workpiece from the selected one of the plurality of marking stations.

2. The marking system of claim 1 , wherein at least one of the blank workpieces is labeled with a blank workpiece identification code, the marking system further comprising:
a workpiece scanner configured to scan the blank identification code and send the blank workpiece identification code to the control system.

3. The marking system of claim 2 , wherein the control system is configured to select the one of the plurality of marking stations based on one or more of a size, a shape, a material, or a marking technique associated with the blank workpiece identification code.

4. The marking system of claim 1 , wherein the control system is configured to identify the product image data based on the blank workpiece identification codes, and control the selected one of the plurality of marking stations to produce the product image on the workpiece based on the identified product image data.

5. The marking system of claim 1 , wherein the selected one of the plurality of marking stations is configured to receive data corresponding to the product image from the control system, and mark the workpiece with the product image based on the data received from the control system.

6. The marking system of claim 1 , wherein the control system is configured to select one of the plurality of marking stations based on operating parameters of the plurality of the marking stations or one or more parameters associated with the workpiece.

7. The marking system of claim 6 , wherein the operating parameters associated with the workpiece include a shape of the workpiece, a size of the workpiece, or a material of the workpiece.

8. The marking system of claim 6 , wherein the operating parameters include a marking technology associated with each of the plurality of marking stations.

9. The marking system of claim 6 , wherein the operating parameters include an availability of the plurality of marking stations.

10. The marking system of claim 1 , wherein at least one of the workpieces is not labeled with a blank workpiece identification code, wherein one of the marking stations is configured to mark the product image on the workpiece.

11. The marking system of claim 10 , further comprising a labelling station configured to provide a product identification code on the workpiece after the workpiece is marked with the product image at one of the marking stations.

12. The marking system of claim 1 further comprising one or more loading stations for receiving and storing the one or more workpieces.

13. The marking system of claim 1 , wherein one of the plurality of marking stations includes:
a marking head configured to produce a product image on the workpiece; and
a transport mechanism configured to move the marking head relative to the workpiece during marking of the product image on the workpiece.

14. The marking system of claim 1 , wherein at least one of the plurality of marking stations is configured to print colorant on the workpiece.

15. The marking system of claim 1 , wherein at least one of the plurality of marking stations is configured to etch a pattern on a workpiece using a laser.

16. The marking system of claim 1 , wherein at least one of the plurality of the marking station is configured to engrave or carve a pattern on a workpiece.

17. The marking system of claim 1 , wherein the control system includes an image processor configured to convert the product image retrieved from the data storage into a pixelated resolution corresponding to a scanning resolution of the marking head, wherein the control system is configured to control the marking head based on the pixelated resolution for marking the workpiece with the product image.

18. A marking system for decorating one or more workpieces, comprising:
a plurality of marking stations configured to mark product images on blank workpieces to produce product workpieces, at least some of which have different sizes, shapes, materials, or a combination thereof, wherein at least one of the blank workpieces is labeled with a blank workpiece identification code;
a control system configured to select one of the plurality of marking stations and send product image data to the selected one of the plurality of marking stations;
a robotic manipulator configured to transport a blank workpiece to the selected one of the plurality of marking stations under the control of the robotic manipulator; and
a workpiece scanner configured to scan the blank identification code and send the blank workpiece identification code to the control system,
wherein the selected one of the plurality of marking stations is configured to mark the product image on the blank workpiece based on the product image data which produces a product workpiece,
wherein the robotic manipulator is configured to remove the product workpiece from the selected one of the plurality of marking stations.

19. A marking system for decorating one or more workpieces, comprising:
a plurality of marking stations configured to mark product images on blank workpieces to produce product workpieces, at least some of which have different sizes, shapes, materials, or a combination thereof, wherein at least one of the blank workpieces is labeled with a blank workpiece identification code;
a control system configured to select one of the plurality of marking stations and send product image data to the selected one of the plurality of marking stations, identify the product image data based on the blank workpiece identification code, and control the selected one of the plurality of marking stations to produce the product image on the workpiece based on the identified product image data; and
a robotic manipulator configured to transport a blank workpiece to the selected one of the plurality of marking stations under the control of the robotic manipulator,
wherein the selected one of the plurality of marking stations is configured to mark the product image on the blank workpiece based on the product image data which produces a product workpiece,
wherein the robotic manipulator is configured to remove the product workpiece from the selected one of the plurality of marking stations.

20. A marking system for decorating one or more workpieces, comprising:
a plurality of marking stations configured to mark product images on blank workpieces to produce product workpieces, at least some of which have different sizes, shapes, materials, or a combination thereof, wherein at least one of the w
